1 TI00132R/09/EN/ Products Solutions Services Technical Information Barrier RB223 One or two-channel barrier Loop-powered barrier for the safe separation of 4 to 20 ma standard signal circuits Application Separation of active 0/4 to 20 ma signals from transmitters, valves and adjusters Your benefits Compact side-by-side housing Space-saving one-channel and two-channel version No power supply necessary International Ex approvals ATEX, FM, CSA Can be used up to SIL3 Bidirectional HART transmission Communication sockets for HART + integrated HART resistor for sensor configuration

2 Function and system design Measuring principle Measuring system The passive barrier is used for galvanic isolation of active signal loops (0/4 to 20 ma) in three applications: Transmission from non-ex-areas to Ex-areas, e.g. for active actuators, controllers or indicators Transmission from Ex-areas to non-ex-areas for the linking of active, intrinsically safe loops in the Ex-area to a PLC Transmission of signals (0/4 to 20 ma) from the Ex-area to the non-ex-area when an intrinsically safe transmitter in the Ex-area is supplied by a not intrinsically safe loop power supply in the non- Ex-area The device has an analog input and an intrinsically safe analog output or an output and an intrinsically safe input. As an option the device is available as a 2-channel version. The barrier is used for intrinsically safe operation of sensors, valves and actuators. The device is supplied from the current loop without a separate power supply. The standard instrument has one analog input and one analog output. A two-channel instrument with two analog inputs and two analog outputs is available as an option. Ex to nonex: Active 4-wire sensor, e.g. Promag 50 Passive current input, e.g. RIA15 NonEx to Ex: Passive 2-wire sensor, e.g. TMT162 Active current input, e.g. SPS A
